Description

Integrated work station for goods-to-person sowing and sorting method thereof

Technical Field

The invention relates to the technical field of sorting in logistics storage, in particular to a goods-to-person sowing and sorting integrated workstation and a sorting method thereof.

Background

In recent years, with the rapid development of computers, electronic commerce and the like, a rapid opportunity is brought to the automated logistics storage industry, and an unprecedented challenge is brought to the logistics storage industry.

The current picking mode of supplying goods by adopting a conveying line mainly adopts two modes of goods to a person picking station or a sowing wall:

the first is to use a box type three-dimensional warehouse, the bin is conveyed to a picker by a transmission line, the picker picks the order according to the order, and then the transmission line transports the bin back. The picking stations are typically divided into a single level (1 source to 1 order, 2 source to 4 order etc. mode) or two levels (2 source to 4 order, 2 source to 6 order, 3 source to 3 order etc. mode in fig. 7). The mode has good generality, but the order box supply layer 11 and the source box supply layer 12 need to be distinguished, so the number and the area of the source box stations and the order box stations are fixed, the dynamic adjustment cannot be performed according to different order characteristics and order requirements, the adaptability is poor, the number of the source box stations supplied at the same time is relatively limited, the matched orders during picking are fewer, the probability of picking for multiple times (the average repeated picking hit rate of orders) is lower when the source box is supplied to the picking station every time, so the number of the source box entering and exiting the box type vertical warehouse is more, the flow demand of the vertical warehouse and the flow demand of a conveying line are higher, the overall efficiency depends on the overall supply capacity and the scheduling scheme of goods to people, but the scheduling rigidity is stronger, and the overall picking efficiency is not high. Meanwhile, due to the need of improving the supply capacity and efficiency, for example, the method and system for picking layered goods in patent application No. CN201610825164.7 have a certain picking efficiency higher than that of the conventional picking station, and a double-layer picking station (for example, reference numeral 11 in fig. 7 is a supply layer, and reference numeral 12 is a delivery layer) is adopted, and each layer must be designed with independent supply and delivery output conveying lines and buffers, so the overall process scheme is relatively complex and has a high cost.

The second method is a method for processing orders by a broadcast wall, the broadcast wall is generally designed according to the number of order customers of the wave order, the order is collected according to the wave order before broadcast, all the sources are sorted out when broadcast, a turnover box is emptied, the broadcast process is generally used for centralized batch supply of goods by a B terminal or a small B terminal (a store or a convenience store), the broadcast wall is generally used for the conditions that the service form is relatively fixed and the traffic volume is not fluctuated, is not suitable for the active ordering of the B terminal or the small B terminal needing quick response, and has poor universality. Meanwhile, in the sowing wall picking mode, the workers are required to pick the goods from the conveying line to the sowing wall (or vice versa), a large amount of waist twisting operation causes labor damage, and the operation is not beneficial to the occupational health of the workers and has high labor intensity.

An existing integrated workstation for goods-to-person spreading and picking is shown in fig. 7, a double-layer picking station (a mode that 3 goods sources receive 3 orders and the like) is adopted, but an order box supply layer and a goods source box supply layer (as a reference number 11 in fig. 7 is a supply layer, and a reference number 12 is a delivery layer) need to be distinguished, so that the number and the area of the goods source box stations and the order box stations are fixed, dynamic adjustment cannot be performed according to different order characteristics and order requirements, the adaptability is poor, the number of simultaneous supply of the goods source boxes is relatively limited, fewer orders are matched during picking, the probability of picking multiple times (the average repeated picking hit rate of orders) is low when every goods source is supplied to the picking station, the times of the goods source boxes entering and exiting a box type vertical warehouse are more, the overall efficiency depends on the goods-to-person overall supply capacity and the scheduling scheme, and the picking efficiency is not high; in addition, because each layer must be designed with independent supply and output transmission lines and buffers, the overall process scheme is relatively complex and costly.

As shown in fig. 1 to 5, according to a preferred embodiment of the present invention, an integrated work station for goods-to-people sowing and picking is provided, which includes at least one picking platform 2, an empty box buffer 4, an output layer-changing elevator 3, conveying lines, a control system (WCS system, not shown in the drawings), an input line 1 and an output line 5. Briefly stated herein, the order type is placed and the workstation is adapted for multiple source case-to-multiple order cases (i.e., picking items from multiple source cases to multiple order cases), one source case-to-multiple order cases (i.e., picking items from 1 source case to multiple order cases), and multiple source case-to-one order cases (i.e., picking items from multiple source cases to one order case).

The conveyor lines comprise a main conveyor line 6 for supply and discharge and a plurality of auxiliary conveyor lines 7.

A main conveyor line 6 having a first end and a second end. The first end is inputted into the source box from the external access area (such as a box type vertical warehouse) through an input line body 1. The second end outputs the order box on the conveying line to an output line body 5 through an output layer-changing elevator 3, and then the order box is conveyed to the outside.

The sorting platform 2 is provided with a plurality of layers of shelves 2-1. Each level of shelves 2-1 has a plurality of stations including a source box station 8 and an order box station 9. The source box station 8 and the order box station 9 are dynamically allocated by the control system (WCS system) according to the order requirements.

Each layer of goods shelf 2-1 is correspondingly provided with one conveying line, wherein one conveying line is a main conveying line 6 (the main conveying line 6 is generally arranged at a height which is convenient for picking up according to ergonomics), and the rest conveying lines are auxiliary conveying lines 7.

The empty box buffer area 4 is arranged at one side of the picking station close to the first end of the main conveying line 6, and empty order boxes are input from the outside in advance through the input line body 1 and a transfer device 4-1; buffer for empty order boxes to be sorted. Therefore, the empty box input of the empty box buffer area 4 and the goods source box input of the main conveying line 6 share the same input line body 1, line body resources are fully utilized, and cost is saved.

The control system dynamically distributes a goods source box station 8 and an order box station 9 for the picking station according to order demands; in response to the arrival of the source box at the source box station 8 and the arrival of the empty order box at the order box station 9, a picking prompt instruction is issued through the auxiliary devices 2 to 4, so that the picking party picks the goods in the source box into the empty order box according to the picking prompt instruction.

The auxiliary devices 2 to 4 include at least one of a display screen, an electronic display tag, a laser pointer and a voice broadcaster. In this embodiment, each station is provided with one of the above-mentioned auxiliary devices 2-4, and an electronic display label with an indicator light, a confirmation key and a display screen is installed at a position corresponding to each station.

In the embodiment, each station of the sorting station is provided with a box position detection device 2-3 electrically connected with the control system, and the box position detection devices are used for detecting the arrival conditions of the goods source box and the empty order box at the station and feeding back the arrival conditions to the control system. In the present embodiment, the tank level detecting device 2-3 is a pressure sensor, but those skilled in the art may select other types of sensors according to actual needs, such as a weight sensor, a photoelectric sensor, etc.

In some preferred embodiments, as shown in fig. 1 and 4, at least one of the stations of the picking station is provided with a transfer machine 2-2, the transfer machine 2-2 being used to transfer source and order boxes from the conveyor line to the picking station 2 and/or from the picking station 2 to the conveyor line, further reducing labor intensity. As shown in fig. 1, in some embodiments, 2 transfer machines 2-2 (one of the transfer machines 2-2 is not shown) are provided at the middle position of the picking station, and when the number of source bin positions required in real time is less than or equal to 2, the two middle positions are preferably designated as the source bin positions 8, and the rest are the order bin positions 9. In some embodiments, as shown in figure 4, each station is provided with a transfer machine 2-2, although the cost of the picking station is increased, the degree of automation is higher and the corresponding picker is less labour intensive.

As shown in fig. 6, the work flow of the foregoing workstation is as follows:

in a first step, the control system receives the order requirements and distributes all or a portion of the orders to the picking stations in response to the order requirements. And meanwhile, dynamically distributing a goods source box station 8 and an order box station 9 for each picking station according to the order, and establishing a corresponding relation among the order, the goods source box identification, the goods source box station 8, the goods of the goods source box, the order box identification, the order box station 9 and the goods to be picked of the order box, wherein the goods comprise the goods identification and the corresponding quantity thereof.

And secondly, dispatching the source boxes from the box type vertical warehouse to the main conveying lines 6 of each picking station according to the order sequence, and conveying the source boxes to source box stations 8 (conveying the source boxes to the source box stations 8, wherein the operation can be finished by manual operation or by controlling the transfer machine 2-2 through a control system). The source box arrives at the source box station 8. Meanwhile, the control system judges whether the empty order box reaches the order box station 9 through the box position detection device 2-3,

a. if the order box is ready, the control system sends a picking prompt instruction to the electronic tags on the station 8 of the source box and the station 9 of the order box, and prompts the quantity to be picked; and (3) picking the goods from the corresponding source boxes by a picking party (such as a worker) according to the picking prompt instruction and the quantity prompted by the electronic tags on the order box stations 9, putting the goods into the order boxes, pressing the electronic tags to confirm that the current picking operation is completed, repeating the operation until all the order boxes hitting the source boxes are picked, and calling the source boxes out of the picking station from the source box stations 8 by the control system. In some embodiments, the sorted source boxes, if empty, may also be stored as new empty order boxes in the empty box cache 4, and the control system records the new empty order box identification for subsequent sorting as empty order boxes.

b. If not, the control system prompts the empty order boxes in the empty box buffer area 4 to be manually supplemented to the corresponding order box stations 9 through the electronic tag, and after the empty order boxes are confirmed to be completely supplemented through the box station detection devices 2-3, the control system binds the supplemented empty order boxes with the orders. The control system issues a picking prompt instruction through the auxiliary devices 2-4; and the picking party picks the goods in the goods source box to the corresponding empty order box according to the picking prompt instruction, the specific process is the same as the step a, and the detailed description is omitted.

Thirdly, when the control system judges that the order box is full or the goods corresponding to the order are completely picked, the work station lights the electronic tag of the corresponding station to prompt the staff to manually push the order box to the rear conveying line or the control system controls the transfer machine 2-2 to automatically convey the order box to the rear conveying line: then the order boxes which have finished the picking task are transferred to an output line body 5 through an output layer-changing elevator 3, and the delivery line body delivers the order boxes which have finished the picking task to the outside.

It should be noted that the foregoing scheduling sequence of the source box and the empty order box (i.e., the sequence of reaching the source box station and reaching the order box station) is not limited in the present technical solution; the order boxes can be dispatched to the order box stations first, the source boxes can be dispatched to the source box stations first, and of course, the order boxes can be dispatched to the order box stations and the source boxes can be dispatched to the source box stations simultaneously according to actual requirements.

In summary, the number of source bin stations 8 and their location on the shelf 2-1 are not fixed, and the number of bins in the prior art double-deck picking station (e.g., 4-bin-to-4-order mode, i.e., having 4 bins) is fixed; in the picking station of the multi-layer goods shelf 2-1, if 4 layers exist, each layer has 4 stations, and the total number of the stations is 16; if the order is an order with a plurality of source boxes and a few order boxes (for example, 14 source boxes correspond to 2 order boxes), the quantity of the source boxes supplied in the same time period is large, the matched orders during picking are large, the average repeated picking hit rate of the order is greatly increased (the repeated picking means that after the source boxes complete 1-time picking task, other order boxes hit the source boxes, namely the same source box supplies the order boxes), the number of times that the source boxes come in and go out of the box type vertical warehouse is reduced, and the overall efficiency is improved. In addition, a main conveying line 6 is adopted, the goods source boxes are input from one side, the empty order boxes are input into the empty box buffer area 4, the goods source boxes and the order boxes with the residual goods sources are output from the other side, independent conveying lines and independent buffers for supplying and outputting are not needed to be designed on each layer, the flow demand on the conveyor is relatively low, and the cost is reduced. Meanwhile, the workstation can flexibly allocate the goods source box position and the order box position according to the order characteristics and the order requirements, so that the order adaptability of the workstation is enhanced; compared with a broadcast type picking station, the method has the advantages that the method does not need to determine the service form and the service quantity in advance, only needs to pick according to the current order, and is strong in universality.

In some preferred embodiments, as shown in fig. 4, an input transfer elevator 10 is also included in electrical communication with the control system for externally inputting empty order and source containers to respective conveyor lines and/or transferring empty order and picked empty source containers between the conveyor lines. In this way, after the source container reaches the first end of the main conveying line 6, the source container can be directly conveyed to the conveying line of the layer where the target source container station 8 is located by the input layer-changing elevator 10; then the control system sends a prompt instruction to the auxiliary device 2-4 (such as an electronic tag), and a picking party (such as a worker) manually pulls the source box from the rear conveying line to the source box station 8 or controls the transfer machine 2-2 to automatically transfer the source box from the rear conveying line to the source box station 8. Similarly, empty order boxes can be directly conveyed to a conveying line of a layer where the target order box station 9 is located from an external empty order box storage area or an empty box cache area 4 through the input layer-changing elevator 10, then the control system sends a prompt instruction to the auxiliary device 2-4 (such as an electronic tag), and a picker (such as a worker) manually pulls the empty order boxes from a rear conveying line to the order box station 9 or controls the transfer machine 2-2 to automatically transfer the empty order boxes to the order box station 9 from the rear conveying line. In some embodiments, if the source container after the picking is completed is empty, the original empty source container may be further transferred to the first end of the main conveyor 6 by the input transfer elevator 10, and the original empty source container is transferred to the empty buffer 4 by the transfer device 4-1 and stored in the empty buffer 4 as a new empty order container, and the control system records the identification of the new empty order container for the subsequent picking as an empty order container.
